Aluminum 600V URD cable is designed for use in secondary distribution circuits, where installed in duct or direct burial applications. Maximum operating temperature is not to exceed 90°C in wet and dry locations. Voltage rating is 600 volts. As an option, this cable can provided pre-pulled into duct.
Aluminum 600V URD cable has a concentric strand or compressed 1350-H19 series aluminum conductor. Conductors are cabled together, with surface printing for identification. The neutral conductor has a yellow stripe.
Aluminum 600V URD cable has a black cross linked polyethylene (XLP) insulation.

Frequently Asked Questions - Triplex Aluminum URD
Can the Triplex Aluminum URDcables be buried directly in the ground?
Yes, Triplex Aluminum URD cables can be buried directly in the ground. It can also be installed in an underground duct.It has been developed in such a way that it can be used in congested areas and is easy to install. Since it is low smoke and flame cables, it can be used both in wet and dry places.
Is TriplexAluminium URD better than copper wires?
There are more valuable reasons why Triplex Aluminium URD is better than copper.
The reasons are:
- Triplex Aluminum has been developed to such great extent since its advancement in aluminium alloys in1970.
- It is the best material to use in transmitting electricity.
- Aluminum is lighter in weight
- It is economical. Low voltage feeders are extensively used by engineers and contractors because it is cheaper than copper.
- It performs equally to copper wire and can be used as an alternative.
- It has same metallic creep as copper
- It is outstanding and withstands any weather condition
- It is designed to be flexible and built for elasticity.
Do Triplex Aluminium URD building wires take much area than copper?
Triplex aluminium URD does take some area, even though it is lighter and weighs only half the weight than copper wires. They are compressed to bring down the size of diameter to use as an alternative tocopper. Though it takes some area, the important thingto notice is, it offers the greatest flexibility and service life than copper wires.
Is there a possibility, that during installation the Triplex Aluminium URD cables likely to get damaged?
Since Triplex Aluminium URD cables are lighter in weight than copper, it has lower pulling tension. This protects the cable from getting smudged or smeared during installation. It can withstand high elongation without any damage. Pulling tensions do not interferewith the performance of the cable. It will not de-laminate even during harsh bends. In some cases, where it has to be pulled, the use of pulling lubricants can reduce damage and lessen pulling tensions.
Does duct size matter with each Triplex Aluminium URDcable?
Yes, appropriate duct types should be used to increase performance of the cable.
Ducting can affect the pulling operation. Duct type should match the internal diameter of the duct to suit the cable. The internal finish of the installed ducting should be even to avoid cable being damaged during installation. Caution should be exercised while choosing ducts for any Triplex aluminium URD cables.
